Room Compensation Control
If you’ve placed speakers close to the wall or in a
corner, you’ll be hearing too much loud low frequency
level. In the case of some studios, there is bass-trap
for reducing the low frequency level. The Room
Compensation Control allows you to lower the bass
range depending on the room acoustics. You can
select the switch to reduce low frequency level in 3
steps of -2dB below 500 Hz. The following graph
shows how Room Compensation Control affects the
response of the speakers.

Cut-off Low Frequency Control
You can use this switch to adjust the bass roll-off in a
multi-channel surround system, or to balance your
room resonance. A subwoofer makes a deep, low
frequency sound.
You can mix how a sub and BLOW5 harmonize using
the Cut-off Low Frequency Control. Flat, -80Hz
and -100Hz are the selections.

Control affects the bass response of the speakers.
